@carybryston - I have owned Kimber 8tc and went on to develop my own speaker cables, which were superior to the 8tc and even the 12 tc in every respect.
I tend to read a lot about other cables to see what design approach they have taken.
- Zavfino make use of OCC copper and low dielectric constant insulation and a more complex cable geometry
- this is the same approach I have taken with my own cables,
- so even though I have not used Zavfino, I have a very good idea of their performance capabilities
- I've also heard from other that use zavfino and they conrfirm their performance characteristics as being very similar to my own cables
- full spectrum with very detailed bass
- low noise floor with superb details and clarity
- very neutral sounding
- fast and fluid dynamic performance
My own cables are designed for the DIY community i.e. I do not build them for sale to others, but I do recommend Zavfino cables to those who feel the DIY approach is not for them.
From that perspective I believe any of the Zavfino lineup will prove to b a good upgrade
You could also look at Audio Envy cables, again they follow robust design principles and will outperform the Kimber products.
Both brands are very well suited to high current solid state designs
